Domenech was born in Barcelona in 1952, he was educated towards a future working in the family's carpentry business. Tutored by his fathers friend in technical design he then went on to educate himself in woodwork. Following this he spent time at the Tarrega Academy learning to draw and perfecting the technique of charcoal drawing. He then went on to study at the Masana School in Barcelona for a further three years.
Domenech devoted himself to becoming a full time artist in 1989 after leaving his carpentry business. His figurative pastel and charcoal work focuses beautifully on the soft tones of the human form and his ability to create a textured softness is distinctive of his work. Gallery Sara Pares in Barcelona and other presigious Spanish Galleries have exhibited Domenech's work.
